Filed: 1991-07-12
Abstract: PURPOSE:To obtain a molded foam usable as a lightweight engineering material which has an excellent balance between mechanical properties and heat resistance and is uniform in foam structure and mechanical property by subjecting a specific copolyester to foam molding. CONSTITUTION:Foam molding is conducted using a copolyester or a composition obtained by mixing a copolyester with at least one ingredient selected from a filler, an organic-polymer flame retardant, and a thermoplastic polymer. The copolyester is constituted by the structural units shown by formulae I to IV, with units I and II accounting for 80-93mol% of units I, II, and III, unit III accounting for 20-7mol% of units I, II, and III, and the molar ratio of unit I to unit II being 78:22 to 3:7. The copolyester has a melting point (Tm,  deg.C) satisfying relation V (wherein X is the proportion (mol%) of unit III to units I, II, and III), has an inherent viscosity of 1.0-3.0dl/g, and shows melt anisotropy. Thus, a molded foam is obtained which has been greatly improved in anisotropy to show good isotropy in mechanical property and is useful as a lightweight engineering material.

IPC: H04N1/393
Filed: 1984-08-20
Abstract: PURPOSE:To obtain record with different dot density by controlling timing in the rotation direction of a photosensitive drum of optical fiber tubes and a direction crossing it at right angles. CONSTITUTION:A character shown in a figure (a) is of minimum recordable size and is in 3:4 proportion of the same side to a character in a figure (b). For example, the character in the figure (a) is obtained by programing three in a program counter, and the character in the figure (b) is obtained by programming four. Then, the time differences ta and tb between adjacent dot signals are at 3:4. When a character is expanded laterally, the interval between adjacent dot signals is varied according to the value programmed in the program counter; when the minimum lateral size of a character is regarded as one, characters whose lateral sizes are 4/3, 5/3, 6/3...16/3 times are obtained. When a character is expanded longitudinally, the time up to the next sweep start is selected properly to expand the character because the drum rotates at a constant speed.

Filed: 1987-07-13
Abstract: PURPOSE:To decrease the storage burden of radioactive waste storage equipment by melting away the surface layer part of a used radioactive material adsorbent by an acidic material to decrease the dose thereof, then packing the same into a drum can. CONSTITUTION:The radioactive material adsorbed on the radioactive material adsorbent 11 is mostly distributed in the surface layer thereof.

Title: Production of hexachlorodisilane
Inventor: KURODA YASUO
IPC: C01B33/107
Filed: 1985-08-08
Abstract: PURPOSE:To obtain Si2Cl6 in high yield without the problems such as temp. control of a reaction zone in dry reaction and treatment of dust by using a reactive medium of liquid in which an antimony chloride compd. is made to exist in the titled process for production consisting in chlorinating an alkaline earth silicide by chlorine. CONSTITUTION:The antimony chloride compd. (SbCl3 or SbCl5) is added to the liquid (L) which is inert with chlorine. The alkaline earth metallic silicide is added to such compd. so as to be kept suspended therein. The chlorine is introduced by bubbling, etc. to such reactive medium. The liquid L having 50 deg.C b.p. is preferable as the liquid having the excessively low b.p. induces evaporation by reaction heat and makes laborious the operation. Si2Cl6, Si3Cl8, Si2Cl6O, etc., are usable for said liquid. The halosilane contg. Si2Cl6 formed by the incorporation of the above-mentioned chlorine is separated from the by-product such as alkaline earth metallic chloride and antimony chloride compd. by atmospheric distillation, vacuum distillation or filtration and is further recovered by refining as a high-purity product.

Title: Resin spin welding member
Inventor: SHIBAYAMA TERUTSUGU
IPC: B29C65/06
Filed: 1986-07-23
Abstract: PURPOSE:To prevent warpage and wrinkles from generating on the rear surface of a board by a method wherein the thickness of a flange part in a spin welding member, which is to be welded to a resin board, is gradually decreased toward its outer periphery. CONSTITUTION:The thickness of a flange part 11 is gradually decreased toward its outer periphery in a resin spin welding member having the flange part 11, a columnar body 10 and engaging projections 12 to be engaged with a rotary jig. Because the flange part gets thinner to its outer periphery side, the outer periphery side of the flange part follows the deformation of the board at the cure shrinkage, even when the linear expansion coefficient of the flange part is different from that of a mounting board 17, resulting in preventing the phenomena of so-called 'heat transfer to rear surface' or of the generation of warpage and wrinkles on the rear surface of the board from developing.
